A waste broker arranges the recovery or disposal of waste on behalf of the company that produces it: it finds the right authorised final treatment facility, prepares the paperwork and coordinates transport, even though it doesn’t treat the waste at its own premises. A broker makes sense when you have several waste streams, when it isn’t clear which destination is most suitable, or when you don’t want to depend on a single plant. If you produce a single, stable waste stream and already have a final treatment facility that suits you, going direct is also a good option.
What is a waste broker under Spanish law?
Spain’s Law 7/2022 on waste and contaminated soils distinguishes between two roles that are often confused:
- Broker (agente): someone who arranges the recovery or disposal of waste on behalf of others, even if they never take physical possession of it.
- Dealer (negociante): someone who buys waste and then sells it, acting on their own account, again without needing to take physical possession of it.
Both must notify the environmental authorities of their activity and be entered in their register. In Catalonia that is the Catalan Waste Agency, and that is where you can check that a broker is authorised.
What is the difference between a broker and a final treatment facility?
They don’t compete: they need each other. The final treatment facility is the one with the installation, the technology and the authorisation to treat a particular waste. The broker doesn’t replace it; it works with several final treatment facilities and chooses, for each waste stream, the one that fits best.
| Aspect | Final treatment facility | Waste broker |
|---|---|---|
| What it does | Treats the waste: recycles it, recovers it or disposes of it | Organises its management: destination, paperwork and logistics |
| Facilities | Its own authorised plant | Doesn’t need a treatment plant |
| Hazardous waste | Appears on the documentation as responsible for treatment | Coordinates; the final treatment facility appears on the documents |
| Non-hazardous waste | Appears as the waste management company | Can appear as the broker |
| Scope | The waste its authorisation and technology allow | Several approved destinations for each waste stream |
What does a waste broker do day to day?
The work starts before the first collection and doesn’t end with it:
- Assessing the waste stream: the process it comes from, volume, frequency, physical state and history.
- Characterisation: EWC code (European List of Waste), hazardousness and, if needed, analysis at an accredited laboratory.
- Choosing the destination: a map of viable final treatment facilities and a comparison of gate fees, transport and documentation requirements.
- Paperwork and logistics: waste acceptance form, waste tracking sheet, packaging, labelling, transport and, where applicable, ADR (the rules for carrying dangerous goods by road).
- Close-out and review: a case file closed for each batch and, in every cycle, proposals to segregate better, change destination or reclassify a waste from hazardous to non-hazardous.
We explain what each of those steps looks like when the waste is hazardous in how hazardous waste is treated.
When should you use a broker, and when should you go direct to a final treatment facility?
| Your situation | What usually works best |
|---|---|
| A single waste stream, steady and high-volume, with your own environmental department | Going direct to the final treatment facility |
| A waste that only one facility in your area treats | Going direct, or using a broker to help with the paperwork and logistics |
| Several different waste streams, hazardous and non-hazardous | A broker to bring contracts, collections and paperwork together |
| New, infrequent or hard-to-classify waste | A broker to characterise it and find it a destination |
| Reliance on a single destination whose terms may change | A broker with active approved alternatives |
Many companies combine the two: they go direct to the final treatment facility with their main waste stream and entrust the rest to a broker.
What should you ask before hiring a broker?
| Question | Why it matters |
|---|---|
| Is it authorised and on the register? | It’s the first thing an inspection will check |
| Did it ask about your process before quoting a price? | Without knowing where the waste comes from, it’s impossible to classify it or choose a destination |
| Does it work with more than one destination for your waste? | That’s what protects you if a destination changes its terms |
| Does it break down the facility’s fee, transport and its own service? | It lets you compare the total cost with going direct |
| Does it give you the full documentation for each batch? | It’s your proof of compliance to the authorities and auditors |
How we work as a waste broker at Alberich
We are an authorised waste broker, with authorisation from the Catalan Waste Agency covering hazardous and non-hazardous waste. Because we aren’t the final treatment plant for that waste, we start from the waste, not from a facility: we choose, from several approved waste management companies, the one that best fits each stream. For hazardous waste, the final treatment facility is the one named on the documentation; we coordinate acceptance, ADR documentation and logistics with our own fleet.
A real example: a chemical manufacturer produced a liquid waste containing formaldehyde that was classified as hazardous. When it changed its formulation and replaced the formaldehyde with an inert plant-based alternative, we suggested a laboratory analysis and a re-characterisation of the waste stream. The process was long, but the waste was reclassified as non-hazardous and the company’s ISO 14001 environmental indicator improved.
As well as being a broker, we are an authorised waste management company (waste management authorisation no. E-345.97 from the Catalan Waste Agency), with our own lines for metals, WEEE and transformers and three sites of our own in Castellbisbal, La Llagosta and Constantí. Many customers entrust us with their scrap and metals, which we buy, and, through our brokerage service, the rest of the waste from their plant, all with a single point of contact. We are a team of more than 170 people and have been in the industry since 1900.
What we don’t do: environmental permits, substantial permit modifications or soil remediation, which are a matter for specialist regulatory consultancies. Clinical waste isn’t our focus either: if a case requires it, we coordinate with specialist operators.
Frequently asked questions
Does hiring a broker make waste management more expensive?
The broker charges for its work, so the fair comparison is with the total cost: the facility’s fee, transport, paperwork and your team’s time. By grouping collections, adjusting frequencies or finding a more suitable destination, the total can come out the same or lower. Always ask for a breakdown.
Who is responsible if something goes wrong with the treatment?
The final treatment facility is responsible for the treatment it carries out at its installation. You, as the producer, are responsible for classifying the waste correctly and handing it over to someone who is authorised, and Law 7/2022 keeps you responsible until its complete treatment has been documented. The broker helps you meet that obligation and respond if there is an incident, but it doesn’t take on your responsibility as the producer.
Do you only work in Catalonia?
Mainly, yes: that’s where we have our three sites, our fleet and a documentation workflow built on the Catalan Waste Agency’s system. Outside Catalonia the documentation framework is different, so we look at each case before committing.
Do you work on recurring contracts or only one-off jobs?
Both. Many customers have collections every month, every two months or every quarter, and we also organise scheduled campaigns, such as cleaning drainage pits and lagoons during the planned shutdowns in August and December.
If you’d like to know whether a broker would add value in your case, send us a list of the waste you produce, with approximate volumes and frequencies, and we’ll reply within 48 working hours.
